Operational Amplifier Series
AutomotiveGround Sense
Operational Amplifiers
BA2904Yxxx-C, BA2902Yxx-C
●General Description
●Key Specifications
BA2904Yxxx-C,BA2902Yxx-C integrate two or four
independent Op-Amps and ground sense input
Amplifier on a single chip. These Op-Amps have some
features of high-gain, low power consumption, and can
operate from +3V to +36V (single power supply ).
BA2904Yxxx-C, BA2902Yxx-C are manufactured for
automotive requirements of engine control unit, electric
power steering, and so on.
